Setup for assessing the susceptibility of a medical device to conducted emissions. The
test involves injecting RF voltages onto the power line and bulk RF currents into other signal cables.
A current probe is clamped around the entire cable bundle, and radio-frequency energy is injected.
The frequency range for conducted immunity tests is 150 kHz to 80 MHz.
